Improvement in blind and shutter fastenings



JACOB FRICK, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVEMENT IN BLIND AND SHUTTER FASTENINGS.

Specification forming part of Letters Patent No. 4l 1,064. dated January5, 1864.

To all whom it may concern,.-

Beit known that l, JACOB FRIOK, of Philadelphia, Pennsylvania, haveinvented an Improved Shutter-Fastener; and I do hereby declare thefollowing to be a full, clear, and exact description of thesame,'ret'erence being had to the accompanying drawings, and to theletters of reference marked thereon.

My improved shutter-fastener, which is fully described hereinafter,hasbeen designed with the view of holding a shutter near the wall, ofpreventing the disagreeable rattling which is common to shutters held byordinary fasteners, and of causing the shutter to be projected outwardand turned on its hinges toward the window when released from thefastener.

1n order to enable others to make and apply my invention, I will nowproceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of thisspecification,

Figure I is a side view of my improved shutter-fastener; Fig. 2, asectional View; Fig. 3, a front view, and Fig. 4 a section on the line 12, Fig. 2.

Similarletters refer to si milar parts throughout the several views.

The line A represents the front of the wall to which the shutter issecured, and B the edge of the shutter.

The fastener consists of the two main parts D andE, joined together by apin, e, the part D having a shank, a, (shown by dotted lines,) which isdriven into the wall, and having a hollow cylindrical projection, I),within which is a rod, c, connected by a pin,f, to the piece E at apoint distant from the pin e. The rod c terminates at the lower end iu adisk, d, against which the spiral spring g bears, and thereby serves todepress the rcar of the piece E, and toY maintain it in contact with thepiece D in the position shown in Fig. 2. It will be observed, onreference to Fig. 4, that the piece E is furnished with lips or flangesh h, which cover the cylindrical projection b, and prevent rain and snowfrom gaining access to the interior and injuring the spiral spring g. Tothe rear of the piece E is secured a bent spring, F, which bears againsta plate, Gr, at the back of the shutter B. The front part of the piece Econsists of a rounded projection, i', which terminates at the shoulderx, against which the front of the shutter B is caused to bear by thespring F.

One of the main objects of my invention has been to prevent thedisagreeable rattling to which shutters are liable when secured byordinary fasteners. 'The spring F maintains the shutters at a distancefrom the wall and in contact with the shoulder so that it would requiremore than an ordinary high wind to cause the shutter to rattle in itsfastener. hatever tendency the shutter may have in extreme cases toforce back the spring and rattle against the shoulder x, the noise whichwould otherwise be caused is obviated by the introduction of a piece ofcork or gumelastic, q, into the shutter at the point where it bearsagainst the shoulder. A similar piece of cork, gum-elastic, or otherlike material may also be inserted into the shutter at q.

Another advantage of my improved shutter-fastener is this-that themoment the rounded projection t' is depressed, the spring F, acting onthe rear of the shutter, pushes the latter away from the wall and turnsit to a position in front ofthe window, thereby obviating the necessityfor pulling the shutter round on its hinges.

I claim as my invention and desire to secure by Letters Patent- 1. Thepieces D and. E, constructed, joined together, and operatingsubstantially as described, i'or the purpose specified.

2. The piece D, with its hollow cylindrical projection b, spiral springy, and rod c, connected to the piece E and having a disk, d, the wholebeing arranged for the depression ofthe piece E to the piece D,substantially as set forth.

3. The spring F, secured to the piece E, for operating on thc shutter,substantially as described.

In testimony whereof I have signed my nameto this specification inthepresence of two subscribing witnesses.

JACOB FRIOK.
